SIGNALING APPARATUS FOR CABLE STREET-RAILROADS.

SPECIFICATION forming art of Letters Patent No.,388,459, dated August28, 1888.

Application filed January 19, 1888. Serial No. 261,271.

To aZZ whom it may concern.-

Be it known that I, HENRY W. SMITH, a citizen ofthe United States,residing at the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Improvement in Signaling Apparatus forCable Street- Railroads, of which the following is a full, clear, andexact description.

Myinvention relates toimproved means of signaling on cablestreet-railroads, whereby a car on arriving at and passing a certainpoint on the track causes a signal or notification thereof to betransmitted to the gripman of another car on the arrival of the latterata corresponding point on a cross-track and at the same time warnspedestrians and drivers of vehicles of the approach of the signalingcarto the crossing, thereby avoiding the danger of collisions.

My invention consists in the application within the respectivecable-tunnels of crosstracks at certain distances from a crossing of aseries of pivoted spring armsor levers, one of which to each trackfarthest from the crossing is provided with a locking device, saidlevers being connected with each other, respectively, by chains or cordspassing round and fixed to sheaves or pulleys, in combination with thegrip attachment of the dummy car and with a pivoted lever thereon, thewhole operating to sound a gong or bell at thecrossing and a gong orhell on the dummy, so that when a car arrives at and passes the leverson either cross-track these levers are thereby vibrated and sound thegong or hell at the crossing, and at the same time the vibration of oneof the outer levers farthest from the crossing moves the outer lockingarm or lever on the cross track into such position wherein it isautomatically locked that on the arrival and passage of a car thereatthe gong or bellon its dummy is thereby sounded.

On the accompanying drawings, Figure 1 is a plan representing the seriesof levers and combined mechanism forming part of my improved signalingapparatus as applied within the cable-tunnels; Fig. 2, a transversesection through the tunnel, showing the relative loca- (No model.)

tion through one of the lovers, following line.

1 l in Fig. 7 Fig. 9, a vertical cross-section through the pulleys andgong on line 2 2 in Fig. 1; and Fig. 10, a general plan, on a reducedscale, showing the adaptation of my invention to a double crosstrack,like letters of reference denoting like parts in all the figures.

a I) represent arms or levers of the first order, which are pivoted orfulcrumed horizontally one above the other to a bracket, 0, affixed tothe inside of the cabletunnel d at a certain distance from the crossinge. The outer end of the lower arm or lever a,when in its normal positionprojects at right angles with and somewhat beyond thevertioal plane ofthe grip attachment f of the dummy-car, where it is held by aspring,g,extending between the inner end of the lover a and the base ofthe bracket 0. The outer end of the upper arm or lever, b, on thecontrary, is normally inclined outward or away from (toward anapproaching car) that of the lever a, so as to be clear of the gripattachment f and its appendages, and is retained in such position by aspring, h, similar to 9.

At the crossing 6, within the tunnels d d at their junction,are mountedhorizontally in the sense of their rotating two sheaves or pulleys,

ij, (see Figs. 1 and 9,) the pulley i when rotated on its spindle in onedirection winding up a spring, k, and in the other direction allowingthe spring lc to unwind, andthereby actuate a gong or bell, Z, adjacentthereto, the

other pulley, being loose on its spindle and unaffected by the pulley i;or, in lieu of two pulleys, z and j, as shown, a series of fast andthereabout, with the lever a,and, as in the case of the latter, normallyprojects slightly beyond the path of the grip attachmentfat rightangles, in which position it is constrained by a spring, 0, in a similarmanner to the springs g and h, acting on the levers a b.

The arm or lever b, hereinafter termed the locking-lever, is providedwith a locking device (see, also, Fig. 8) composed of a bellcrank, p p,which is fnlcrumed on the locking IO lever b, the end portion of itshorizontal arm passing through and having easy play within the slottedhead or handle of a bolt, q, which is fitted and slides verticallythrough thelocking-lever I). The lower end of the bolt q is normallyconstrained against the upper surface of the bracket 0 by a spring, 1*,fixed to the locking-lever b and bearing against the outer edge of theupright arm 1) of the belt crank. In the upper side of the bracket 0 is20 formed a hole or depression, g, which is located immediately beneaththe bolt q when the locking-lever b is at right angles with the path ofthe grip attachment f.

Within the tunnel d of the crosstrack are 2 5 arranged arms or levers a91/,With their brackets 0 m, springs g h 0, and locking-lever b atcorresponding distances from the crossing c and similar in. all respectsto the correspond ing parts above described.

To the inner end of the arm or lever a is attached one end of a chain orcord, 8, which passes round and is fixed to the sheave or pulley a,whence it extends and is attached at its other end to the outer endportion of the lock- 5 ing'lever b, asimilar chain or cord, 8',extending from the inner end of lever to over and fixed to pulleyito theouter end portion of lockinglever 12. To the inner end of arm or lever ais attached one end of a chain or cord, t,

which passes round and is fixed to pulley j, thence coupled to the outerportion of arm or lever a, and from the latter to the upright arm 19 ofthe bell-crank 11 19 on the locking-lever b, Where its other end isattached. A similar chain or cord, 25, passes from the inner end of armor lever or around and made fast to pulley 1i, thence to outer portionof arm or lever 12 to the upright arm 1) of bell-crank pp onlocking-lever I).

Mounted on its spindle u in suitable bearings, 1), carried by theforward end of the grip attachmentf, is an arm or lever, w, whichdepends vertically at such a distance from one side of the gripattachmentf that in traveling with the latter its forward edge comes incontact with the end rear edge portion of the locking-lever b (or I), asthe case may be) when this is in a position at right angles with thepath of the grip attachmentf, as hereinafter more particularlydescribed. On the spindle a of the arm or lever to is fixed a drum orsheave, x, to the circumference of which centrally, at top or in linewith the lever w, is attached one end of a chain, cord, or wire, g,which extends upward above the floor of the dummy,

and is attached at its other end to a springbarrel, 2, for actuating thegong or hell 2, carried on the grip or other convenient place in thecar.

The operation of my invention is as follows: The various parts being intheir normal positions, as described, and a car approaching the crossing6 along, say, the track d, as indicated by arrow 1 in Figs. 1 and 7, theforward part of the grip attachmentf strikes the end of the arm or levera and carries it over horizontally about its fulcrum into the positionshown by dotted lines in Fig. 1. This causes the cord 8 to be pulled inthe direction of arrow 2, par tially rotating pulley i, as arrow 3,thereby winding up spring is and pulling the cords on the other track,(1, in the direction of arrow 4, so as to pull over the locking-leverI), as arrow 5, into a position at right angles with the path of thestriking-lever w on the grip attachment of another car which may beapproaching that point on the track d, in which position thelocking-lever b is locked by the springing of the bolt g of its lockingdevice into the hole therefor in the bracket 0. Simultaneously by themovement of the pulley i the cord 8 on track (Z is pulled, as arrow 6,and throws over the locking-lever b, as arrow 7, into the lockedposition or at right angles with the path of striking lever w on thegrip attachmentf, the cord s on the track d/ falling slack. On the gripattachmentf clearing the lever a the latter is returned by its spring 9to its original position,and the spring is, being thereby allowed tounwind, sounds the gong or hell Z and returns the pulleyt' to its normalposition, thereby tightening cord 8 and slackening cord 8 on track d,and slackening cord 3 while tightening cord 8 on track d. On the arrivalof the car at the intermediate arm or lever, n, the grip attachmentfstrikes and throws over the lever n into the dotted position, and in sodoing pulls upon cord t, as arrow 8, partially rotating pulley j, asarrow 9, and, pulling upon cord t on track (1', as arrow 10, throws overthe bell-crank 19 12 so as to withdraw the bolt g from the bracket 0,and so release the locking-lever b. Simultaneously cord t on track d ispulled, as arrow 11, and withdraws the bolt 0 of the locking-lever b,which is thereby also released. On the grip attachmentf clearing lever athe locking-levers b b are returned to their normal positions clear ofthe paths of the grips by their respective springs hh. Now, by theforegoing arrangements, if a second car should arrive at thelocking-lever b on the other track, d, while the first car on the trackd is passing between the levers a and n, the locking-lever b,being inthe locked position or at right angles to and in the path of thestriking-lever w on the grip attachment of this second car, is struck bythe striking-lever w, and the latter is thereby vibrated backward, and,partially rotating the drum or sheave a: on its spindle it, pulls downthe cord or wire y, so as to wind up the spring-barrel z of the gong orbell z on the dummy. On the strikinglever w clearing the locking-lever bit is returned to its normal position by the release of the springbarrel-z, which in unwinding sounds the gong or bell z and gives warningto the gripman of the approach of the first car on the track d to thecrossing c.

The same description will apply to a car approaching the crossing 6along the track d in advance of a second car along track 11, theoperation of the parts being the same in re verse order.

In Fig. 10 the principle is shown extended to a double cross-track, d,the parts applied thereto being the same as those to track d, and theoperation thereof transmitted from one to the other by endless bands andpulleys i.

I claim- 1. The combination of an arm or lever having a spring andpivoted to a bracket secured within the tunnel of a cablestreet-railroad, a chain or cord attached to said lever and to a sheaveor pulley, and a spring located between the pulley and a gong orbell,with the grip attachment of a cable-road car, substantially as andfor the purpose set forth.

2. The combination of two outermost arms or levers having springs andpivoted to a bracket within the tunnel of a cable streetrailroad, one ofsaidlevers being provided with alocking device, a chain or cord attachedto each of said levers and to a sheave or pulley, aspring locatedbetween the pulley and a gong or hell, an arm or lever intermediate tothe outermost levers and thepulley, and a chain or cord attached to theintermediate lever and to the locking device of one of the outermostlevers and attached to a sheave or pulley, with the grip attachment of acable-road car and with aleverand spindle mounted thereon, said spindlehaving a drum or sheave from which a cord or wire extends to the springmechanism of a gong or hell on the dummy, substantially as and for thepurpose set forth. i

3. In two cross-tracks of a cable street-railroad, the combination ofthe outermost arms or levers and intermediate lever and their appendagesof one track and the corresponding parts of the other track, chains orcords extending, respectively, between the levers and locking device ofone track to those of the other track and secured to intermediatesheaves or pulleys, and a spring locatedbetween one of said pulleys anda gong or bell, with the grip attachment of a cable road car and with alever and spindle mounted thereon, said spindle having a drum or sheavefrom which a cord or wire extends to thespring mechanism of a gong orhell on the dummy, substantially as and for the purpose set forth.

4. The combination of a lever and spindle mounted on the grip attachmentof a cableroad car, said spindle having a drum or sheave from which acord or wire extends to thespring mechanism of a gong or bell on thecar, with a pivoted lever or other intercepting device within thetunnel, substantially as and for the purpose set forth.

In testimony whereof I affix my signature, in presence of two witnesses,this 16th day of January, 1888.

HENRY V. SMITH.
